BUTTON-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 368,141, dated August9, 1887.

Application filed May 13, 1887. Serial No. 238,107. (No model.)

To all whom it may concern:

Be it known that I, LOENDER O. Ennnson, a citizen of the UnitedStates,residing at North Graftomin the county of \Vorcester and State ofllIassachnsetts, have invented certain new and useful Improvements inButtoirFeeding Mechanisms for Button-Setting Machines, of which thefollowing is a specification, reference being bad therein to theaccompanying drawings.

My invention relates to a button-feeding mechanism for button-settingmachines, the said invention being more especially adapted for operationin connection'with the form of button-setting machine shown by UnitedStates Patent No. 341,053 to F. H. Richards.

In my invention I use a rotary buttoncarrying head or carrier, whichtakes the place of the die'holder in the patent above referred to. Thisrotary head or carrier is provided with a series of retainingsprings forthe buttons and with a series of setting dies or anvils, against whichthe fasteners are forced by the d river to bend them in proper shape tohold the buttons on the shoes or fabrics to which they are to beattached. In connection with the rotary button-carrier-I employ amovable chute or roadway, which conducts the buttons from the box orrcceptaclein which they are contained to the said carrier, and thelatteris intermittingly rotated by a pawl-and-ratchet mechanism connected by arod with the treadle by which the driver is operated. The movablebutton-conducting roadway or chute is reciproeated by a lever operatedby the pawl-carrier, which actuates the rotary button-carrier, and by aretractingspring. The said chute is moved toward the button-carrier, sothat it may force a button into the same when the treadle is operated;but before the chute begins its retreat from the carrier the lattercommences its rotation, and thus removes the button from thespring-holding fingers at the lower end of the chute before the lattermoves away from the carrier. A partial rotation of the I carrier bringsthe button into position to be set at the next blow of the driver, sothat while one button is being set another is being placed in thecarrier preparatory to the setting operation.

In the drawings, Figure 1 is a front view of a button-setting machinewith my invention ap plied thereto. Fig. 2 is a side view of the same.Fig. 3 is a detail plan view showing the button-chute in section in theposition it occupies when placing a button in the carrier. Fig. 4 is apartial section on line 4 4, Fig. 2, and with parts in the same positionas in Fig. 3; and Fig. 5 is a detail view of the buttonchute.

A denotes the frame of the machine, the said frame being in practicesupported by an iron c0lumn,which incloses the treadle-rod for operatingthe driver.

13 is a vertical post in which the driver (not shown) reeiprocates, andC is the magazine to contain the fasteners, all as in the patent abovereferred to.

D is a support or bracket, which is screwed to the frame A, the saidbracket having a dovetailed recess or guideway, d, for the reception ofa dovetailed projection on a slide, E, to which is attached the buttonbox or receptacle F. The button roadway or chute G is attached to thebase-plate f of the button-box F, the said chute having a quarter turnor twist, as shown in Fig. 5, to bring the buttons from their positionwith their heads down, in which they enter the chute, to a positioninwhich the shanks will be horizontal, as in Fig. 3. The said chute isprovided at its lower end with re taining-springsg and g, to prevent thebuttons from falling out and to hold them when being presented to therotary button-carrier. The buttons in the box F are forced into thechute G by an ordinary agitatingbrush operated in any suitable manner.

I is the rotary button-carrying head or carrier, having a shaft, 2',which has a bearing in the top of the frame A, the said shaft having aratchet-wheel, H, engaged by a spring-pressed pawl, 71, pivoted to alever, J, and the latter is pivoted on the shaft 2' and is provided witha roller-stud, h- A rod, J, connects the lever J with the treadle bywhich the driver is operated, and a detent-spring, h", prevents thebackward movement of the wheel H. bracket D has a depending arm orhanger, d, to which is pivoted a bell-crank lever, K, the lower arm ofwhich is in position to be acted on by the roller-stud h on thepawl-carrying The of the said head to receive the heads of the buttons.Opposite each of the springs t" is a setting die or anvil, M,constructed, as shown in the patent referred to, with a recess of properform to bend over or'clinch the fasteners.

The operation of my device is as follows: When the treadle (not shown)is operated, the downward movement of the rod J depresses the outer endof the pawl-carrying lever J, and the roller-stud h thereon engages theinclined outer 'end, k, of the horizontal arm of the lever K, thusturning said lever on its fulcrum and causing the slide E, connected bythe link L to the vertical arm of the said lever, to move to the left,Fig. 1, and thus thelower end of the chute G will move into engagementwith the rotary button-carrier I and place a button in the said carrierbehind one of the holdingsprings t. When the treadle is released, asuitable retracting-spring (not shown) in the supporting column of themachine forces the rod J upward, causing the pawl h to engage a tooth ofthe ratchet-wheel H, and thus give a quarter-turn to thecarrierI,"bringing the button above the post B into position to be set. Duringthe first part of the operating movement of the pawl-carrier (as the rodJ moves upward, as just described) the rollerstud h will traverse thecurved portion of the horizontal arm of the lever K before it rides downthe inclined end-k of the said arm, and th us thesaid lever will remainat rest,with the button'chute still in its forward position, until apartial rotation of the carrier I has been effected and the button hasbeen carried downward out of the lower end of the chute, the springs yand g'yielding to release the lower button from the chute,butimmediately retracting to prevent other buttons from escaping. As the roller-studh rides down the inclined end is of the lever K, the retracting-springN, acting through the lever K, link L, slide E,

and the button-box, (to the base of which latter the button-chute isattached,) returns the chute to its original position. The next downwardmovement of the rod J sets the button now brought into setting positionabove the post B and causes the forward movement of the chute G to placeanother button in the r0- tary carrier Land thus the button feeding andsetting operations will be repeated as rapidly as the treadle can beworked. 1

I do not wish to be understood as limiting my invention to the precisedetails of construction herein shown and described, as such details maybe varied within the limits of me chanical skill without departing fromthe spirit of my invention. Forexamplathe ro' tary head or carrier I,instead of having four button-holding springs and four setting-dies, asherein shown, (and being thus adapted to perform a quarter-revolution ateach operation of the treadle,) might have a greater or less number ofthese springs and dies, and thus be adapted to be rotated through agreater ,or less portion of a circle at each operation of the treadle.

I claim- 1. In a button-feeding mechanism, the combination hereindescribed,with a rotary buttoncarrier provided with button-holdingsprings and setting dies or anvils, of a reciprocating button-chuteadapted to approach the said carrier to place the buttons therein,substantially as set forth.

2. In a button-feeding machine, the combi- .nation, with the rotarybutton-carrier I, having the holding-springs c" and the setting dies oranvils M, of the ratchet-wheel H, the pawlcarrier J ,having the stud l1,the spring-pressed pawl h, the bell-crank lever K, and the movablebutton chute with which the said leveris operative] y connected,substantially as set 'forth.

3. The rotary head or button-carrier I,hav-

ing on its front face the disk '6', of less diameter than the said head,combined with the button-holding springs 1', extending beyond theperiphery of the said disk, substantially as set forth.

In testimony whereof I affix mysignature in presence of two witnesses.
